In the past, if I ever got any ice in a Tote, I just stopped using that one until it just started to melt, then I put new liquid sap in it. From there I pumped it into my SS sap tanks, Any ice remaining just became the refrigeration for the new sap. I'd be very concerned about using non food grade aerators or aquarium pumps. Who knows what they are made of? Remember, syrup is a food product.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
